I had laid coals flat not vertical.
And had the vents too far closed.
Ash fell butt dripped and concrete vent blockage was formed.
The snake I am building tonight will be on my three wheeler.
One vent wide open with no coals above, charcoal will be Stubbs vertical with all voids filled in with lump crumbs.
There will be no sleeping while running this one.
I will be watching it but trying not to mess with it.
Is one bottom vent wide open on the three wheeler enough airflow?
I will be starting bottom right.
Fire up 5am
Wake and smoke.
